Cause
Possible Solutions
Multi-function analog input is set
up to accept gain for the
frequency reference, but no
voltage (current) has been
provided.
• Check the multi-function analog input settings.
• Check if analog input A1 or A2 is set for frequency reference gain (H3-02/10 = 1). If so, check if the correct
signal is applied to the terminal. The gain and the frequency reference will be 0 if no signal is applied to the gain
input.
• Check if H3-02 and H3-10 have been set to the proper values.
• Check if the analog input value has been set properly.
The
STOP
button was pressed
when the drive was started from
a REMOTE source.
•
When the
STOP
button is pressed, the drive will decelerate to stop.
• Switch off the run command and then re-enter a run command.
•
The
STOP
button is disabled when o2-02 is set to 0.
Motor is not producing enough
torque in the V/f motor control
method.
• Ensure the selected V/f pattern corresponds with the characteristics of the motor being used.
• Set the correct V/f pattern to E1-03.
• When E1-03 = F, increase both the minimum and mid output frequency voltages (E1-08, E1-10).
Increase the frequency reference so that it is higher than the minimum frequency reference (E1-09).
Perform Line-to-Line Resistance Auto-Tuning when using particularly long motor cables.
Increase the torque compensation gain (C4-01).
Motor is not producing enough
torque in Open Loop Vector
Control.
• Execute Rotational Auto-Tuning.
• If the motor cables are replaced with longer cables after Rotational Auto-Tuning was performed, Auto-Tuning
may need to be repeated due to voltage drop across the line.
• Check if the torque limit parameters have been set too low (L7-01 through L7-04).
• Reset the torque limit back to its default setting (200%).
Increase both the minimum and mid output frequency voltages (E1-08 and E1-10).
The drive is set for both 2-Wire
and 3-Wire sequence at the same
time.
• The drive is set for a 3-Wire sequence when one of parameters H1-03 through H1-06 is set to 0.
• If the drive is supposed to be set up for a 2-Wire sequence, then ensure parameters H1-03 through H1-06 are not
set to 0.
• If the drive is supposed to be set up for a 3-Wire sequence, then H1-
must be set to 0.

Motor Rotates in the Opposite Direction from the Run Command
Cause
Possible Solutions
Phase wiring between the drive and motor is incorrect.
• Check the motor wiring.
• Switch two motor cables (U, V, and W) to reverse motor direction.
• Connect drive output terminals U/T1, V/T2 and W/T3 in the right order to the corresponding
motor terminals U, V, and W.
• Change the setting of parameter b1-14.
The forward direction for the motor is setup
incorrectly.
Typically, forward is designated as being counterclockwise when looking from the motor
shaft (refer to the figure below).
1
2
1. Forward Rotating Motor (looking down the motor shaft)
2. Motor Shaft
The motor is running at almost 0 Hz and the Speed
Search estimated the speed to be in the opposite
direction.
• Disable bi-directional search (b3-14 = “0”) so that Speed Search is performed only in the
specified direction.
Note:
Check the motor specifications for the forward and reverse directions. The motor specifications will vary depending on the manufacturer
of the motor.
n
Motor Rotates in One Direction Only
Cause
Possible Solutions
The drive prohibits reverse rotation.
• Check parameter b1-04.
• Set the drive to allow the motor to rotate in reverse (b1-04 = “0”).
A Reverse run signal has not been entered, although 3-
Wire sequence is selected.
• Make sure that one of the input terminals S3 to S6 used for the 3-Wire sequence has been
set for reverse.
n
Motor is Too Hot
Cause
Possible Solutions
The load is too heavy.
If the load is too heavy for the motor, the motor will overheat as it exceeds its rated torque
value for an extended period of time.
Keep in mind that the motor also has a short-term overload rating in addition to the possible
solutions provided below:
• Reduce the load.
• Increase the acceleration and deceleration times.
• Check the values set for the motor protection (L1-01, L1-02) as well as the motor rated
current (E2-01).
• Increase motor capacity.
The air around the motor is too hot.
• Check the ambient temperature.
• Cool the area until it is within the specified temperature range.
The drive is operating in a vector control mode but
Auto-Tuning has not yet been performed.
• Perform Auto-Tuning.
• Calculate the motor value and reset the motor parameters.
• Change the motor control method to V/f Control (A1-02 = “0”).
